To all whom it may concern:

Be it known that 1, WILLIAM ROCHLITZ, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a newand useful Improvement in Apparatus for Distilling ater,of

which the following is a specification.

My invention relates more particularly to an apparatus for distillingwater as a means for obtaining simple distilled water, although, ofcourse, the apparatus can be used for any kind of distillation. It isextremely in the art to provide a condenser which is supplied with steamfrom a retort or boiler and submerged in a body of water from which theboiler is supplied, the water in the boiler being kept at a certaindepth by an overflow-outlet and the supplychamber containing the waterwhich surrounds the condenser being fed by a supply-pipe, so that whilethe water will cool the condenser sufficiently for condensing purposesit will also be warmed before entering the boiler.

The object of my invention is to provide various improved features ofconstruction in apparatus based upon the foregoing-described old andwell-known principles, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents in side elevation anapparatus embodying my invention. Fig. 2 is a cross-section on line 2 2in Fig. 1. Fig. 3 is a vertical central section of the apparatus, thestandard L being, however, principally in elevation. Fig. 4 is avertical section through the apparatus on line 4. 4: in Fig. 3. Fig. 5represents in perspective and on a smaller scale the condenser detachedfrom the jacket. Fig. 6' is a side view of the base-clamp for thestandard.

The condenser A is arranged within a cylindric jacket 13, which is ofsufficient diameter to provide a supply-chamber b about the condenser.The chamber 19 is at its lower end provided with a supply-cock O, whichcan be connected with any suitable source of supply by a flexible tubeor other convenient connection. The supply'chamber b is at its upperportion provided with two outlets, the one being a feed-pipe D, leadingto the boiler E, and the other an overflow-outlet arranged to maintainwithin the boiler a comparatively shallow body of water, and therebysecure ready vaporization. The overflow-outlet and pipe D are arrangedto connect with chamber b somewhat below the closed top end I) of thejacket B, so as to provide fora steam-dome or steamchamber 12 arrangedabove and in communi cation with the condenser. The upper portion of theboiler connects with said steam dome or chamber by a short pipe e, sothat steam generated within the boiler may enter the steam-dome andthence pass down into the condenser, as indicated by arrows in Fig. 3.The upper end of the condenser opens into the space or chamber 12 of thesteam-dome, but is closed to the water-supply chamber 1). The condenseris detachablyheld within the supply-chamber, and as a means for thusremovably connecting said members the base a of the condenser isexternally threaded, as at a, and adapted to screw into a threadedbearing b in the lower end of the jacket B, the joint at sncha pointbeing made tight by a jacket or other suitable packing. WVith furtherreference to the removability of the condenser from the supply-chamberthe condenser is at its upper end provided with a coupling-sleeve awhich is open at its top end, but at its lower end closed around thecondenser proper at a point below the top end of the latter. Thecylindric sleeve a is of greater diameter than the greatest diameter ofthe condenser, so as to leave between the two a spaceforacoupling-sleeve F, which is open at both ends and at its upper endunited with the inner wall of the jacket B by an annular flange f.YVhile, therefore, steam from chamber 19 can pass down through thesleeve F and enter the condenser, it cannot pass from said chamber 19into the supplychamber 1). By the foregoing-described arrangement thesleeve a on the condenser can be removably slipped upon the sleeve F ofthe jacket, and hence the sleeve F will be received between the sleeve(0 and the upper end portion of the condenser, which extends up throughthe-closed lower end of its sleeve a and projects upwardly to someextent within the same.

WVhile the coupling-sleeve a could be made to fit close upon the sleeveF,I may, as herein illustrated, provide for a water seal between thecondenser and joint'formed by the two sleeves, and to such end waterspace is left both between the sleeve F and sleeve a and also betweensaid sleeve F and the upper end portion of the condenser, the sleeve Fbeing made of a length to terminate short of the closed lower end ofsleeve a Under the aforesaid arrangement the water-space thus providedwill be partially filled with water of condensation, and hence a sealprovided between the upper end of the condenser and the supply-chamberZ).

The condenser A is of a peculiar form in cross-section and is adapted toprovide large area of internal condensing-surface and a large area ofexternal heating-surface for warming the water within the supply-chamberb. To such end the condenser is made star-shaped in cross-section,asbest illustrated in Fig. 2, by which arrangement it is provided withvertical passages 1 1 and 2 2, which are of narrow oblong shape incross-section and arranged to intersect one another along the verticalcenter 3 of the condenser.

The condenser thus constructed may be said to be star-shaped incross-section, whether the star have four or more points, and hence Ihave hereinafter so designated the condenser-that is to say,I havereferred to it as being made star-shaped in cross-section.

The construction shown in Fig. 1 comprises, as aforesaid, the passages l1 and 2 2, which said passages unite along the vertical center 3 of thecondenser. These vertical passages therefore are in cross-sectionlateral to and arranged to radiate from a common central passage, as at3; and since the side walls of each passage are comparatively closetogether steam entering the same must necessarily descend in thinsheets, and hence be readily condensed. The base a of the condenser isprovided with a suitable discharge-nozzle a and, if desired, the samecan be furnished with a cock.

The overflow is provided with a chamber G, arranged along the outer sideof jacket B and at its lower end connected with the supplychambcr I).The outer side of the jacket forms the back wall of chamber G, as inFig. 4. The chamber Gis provided below its open top with adischarge-nozzle 9, through which the outflow will maintain the waterwithin the supply-chamber and boiler at a proper level.

As a means for providing between the boiler and the supply-chamber apassage connection to which ready access can be had for cleaningpurposes, the supply-chamber b is provided with a lateral extension 11which is connected with the boiler through the medium of the shortstraight feed-pipe D. The feed-pipe has its inlet end arranged toconnect with one side of the extension Z), and the latter is at itsouter end provided with a removable screwplug II, arranged opposite theinlet end of the feed-pipe, so that after removing said plug a cleanercan be introduced into the feed-pipe.

The boiler is provided with a detachable cap 6, which can be removed topermit the boiler to be cleaned, and as a means for economizing heat theboiler is provided with a surrounding jacket I, which is open at ltslower end. so as to expose the bottom of the boiler to the flame from aBunsen burner K or other suitable heating agent. The jacket I isarranged to provide an annular space or passage i around the boiler andis at its upper end secured to an annular flange with which the boileris provided. The jacket is also provided with openings 11' for thepassage of the products of combustion which pass from the burner upthrough the passage 1;.

As a simple, compact, and efiicient way of supporting the apparatus thusfar described, I provide a standard L, either made solid or hollow,(gas-pipe being convenient for the purpose,) and arrange upon the lowerend of the same a clamp I, which can be convenicntly secured upon theedge portion of a table or the like. The standard is substantially thelength of the jacket, and is at its upper end provided with an eye L,which forms a supporting-bcaring for the pipe 6, which connects thesteam -dome with the boiler. The eye L is adapted to permit the pipe toturn within it,and hence while thestandard may be secured by its clampin a vertical position the remaining portion of the apparatus can beswung upon its supporting-bearing L and brought either to an inclined orhorizontal position for cleaning purposes. The standard is also providedwith a bracket M for the burner K, and in order to lock and steady theapparatus while in its normal position I provide the standard with aset-screw N, arranged to engage a bearing a on the jacket, it beingunderstood that the set-screw can be disengaged from said bearing whenit becomes necessary to tilt the apparatus independently of itsstandard.

In order to permit the condenser to be readily unscrewed from thejacket, Isecure on the bottom of the condenser a small bar or oblongplate P, which is bent downwardly at its ends, so that by placing a rodor the like between such ends the same can be turned for the purpose ofunscrewing the condenser.

\Vhat I claim .as my invention is- 1. A distilling apparatus comprisinga condenser, the supply-chamber b, surrounding the condenser andprovided with a lateral enlargement 0 a boiler, a feed-pipe D, arrangedto lead from said lateral enlargement I) of the supply-chamber to theboiler, and a removable plug H, applied for closing an opening formedthrough the side of the lateral enlargement of the supply-chamber at apoint opposite the inlet end of the feed-pipe, suhstantially as and forthe purpose described.
